As usual, I'm sure I'm just missing something here... I can't quite
figure how to do validation of a custom component. I basically want
to do what is described here[0] about using onSuccess(), but in a
component rather than a page. I basically have a PasswordForm
component which itself has a form, and that needs to verify that the
"password" and "confirm password" fields are equal. I'm able to do
this validation in PasswordForm.onSuccess() without any trouble....
String onSuccess() {
if (!password.equals(password2)) {
log.error("Passwords don't match");
form.recordError("Passwords don't match");
return null;
}
}
but how do I notify the containing page that there is an error?
Currently, the page just moves right along after logging my error
message. I've tried throwing a ValidationException from onSuccess(),
but that ends up being displayed to the user with a stacktrace and
all. I even looked at the standard Form component's onAction method
and copied some stuff from there (specifically looking at
_resources.triggerEvent(FAILURE, context, handler)) but that didn't
help at all. I separately tried extending AbstractField and
overriding processSubmission() as suggested in one post, but that
didn't do much for me.
Any suggestions would be much appreciated.
